2. INDUSTRIAL ANTENNA
APPLICATIONS
What is an antenna?
• A transducer which converts Guided EM waves into free space EM waves
and vice versa.
Why we need antenna in industrial applications?
• To establish a communication link between two radios or to acquire the
data from distant location

3. Industrial antenna applications
 Three basic type of antenna applications in
industries are
 SCADA (Supervisory Control And Data Acquisition)
systems
 Wireless communication
 Remote sensing

4. Industrial antenna applications
 SCADA:
 To transmit data from sensors and other devices to the
SCADA system, allowing operators to monitor and
control the infrastructure from a central location.
 Useful in the cases where human intervention is not
possible like nuclear reactor temperature monitor.

5. Industrial antenna applications
 Wireless Communication:
 To establish a communication link between two radio
devices wirelessly.
 Vehicle to vehicle communication, satellite
communication, radio devices communication and
industrial automation systems are some examples.

6. Industrial antenna applications
 Remote sensing:
 The process of detecting and monitoring the physical
characteristics of an area by measuring its reflected and
emitted radiation at a distance.
 Synthetic aperture radar, weather monitoring radar and
ground penetrating radar are examples for remote sensing
of agriculture land, land slides, deforestation etc.,.
